What is the relationship between chromosome numbers in body cells and sex cells?

erik [133]

Answer:

In sexually reproducing organisms, the number of chromosomes in the body (somatic) cells typically is diploid (2n; a pair of each chromosome), twice the haploid (1n) number found in the sex cells, or gametes. The haploid number is produced during meiosis.

Can somebody give me the answer for these...

labwork [276]

Answer:

1. Life cycle of a cell starts from

G1 phase - S phase (synthesise phase) - G2 phase - mitosis.

2. By mitosis bcoz it restore nucleo cytoplasmic ratio means ploidy of cell remain same.

3. Bcoz of transformation of normal cells into cancerous cells by Carcinogens present in tobacco.,drugs .etc

4 mitosis occurs in plants animals

Binary fission occurs in bacteria and other single celled organism.

Both give rise to two daughter cells.

5.sex cells (n) are produced by meiosis from gamete mother cells(2n).

6.in meiosis ploidy of cell become half

Means diploid cell form haploid cells

And 4 haploid daughters cells are formed.

In mitosis, ploidy of cell remain same

Means haploid form haploid and diploid form diploid.

1 cell form 2 daughter cells.

Hope this helps you.. Frnd ❤️

Why did the White House experience water damage ?

bagirrra123 [75]

These sandstones are porous in which rainwater is easily penetrated in it that cause damage to the white house building so it is concluded that the building is made of porous sandstone.

Select all that apply. Mutations _____. are random. delete genes from the gene pool. add new genes to the gene pool. are changes

Svetllana [295]

Mutations are random and rare changes in the DNA sequence that can both add or delete genes. (therefore, all of the answers listed above apply)

In genetics, the term mutation represents any change in the DNA sequence of an organism. Mutations can be limited to a change in just a single nucleotide ( Single Nucleotide Polymorphisms) or it can include deletions, insertions or translocation of a longer DNA sequence, sometimes even whole genes. Mutations are rare and random events, but there are some places in the genome that are more prone to genetic mutations, called ''hot spots''.
